Characterization of calcineurin A and B genes in the abalone, Haliotis diversicolor, and their immune response role during bacterial infection. PeerJ 2020; 8:e8868.

Abstract
Calcineurin (CN) is known to be involved in many biological processes, particularly, the immune response mechanism in many invertebrates. In this study, we characterized both HcCNA and HcCNB genes in Haliotis diversicolor, documented their expression in many tissues, and discerned their function as immune responsive genes against Vibrio parahaemolyticus infection. Similar to other mollusk CNs, the HcCNA gene lacked a proline-rich domain and comprised only one isoform of its catalytic unit, in contrast to CNs found in mammals. HcCNB was highly conserved in both sequence and domain architecture. Quantitative PCR and in situ hybridization revealed that the genes were broadly expressed and were not restricted to tissues traditionally associated with immune function. Upon infection of H. diversicolor with V. parahaemolyticus (a bacteria that causes serious disease in crustaceans and mollusks), both HcCNA and HcCNB genes were highly up-regulated at the early phase of bacterial infection. HcCNB was expressed significantly higher than HcCNA in response to bacterial challenge, suggesting its independent or more rapid response to bacterial infection. Together, the two CN genes are unique in their gene structure (particular HcCNA) and distribution in mollusk species and likely function as immune responsive genes along with many other genes that are enhanced in the early phase of V. parahaemolyticus infection in abalone.

FISH & SHELLFISH IMMUNOLOGY 2015; 43:91-102.

Abstract
Calcineurin (CN), the only Ca(2+)/calmodulin-activated serine/threonine protein phosphatase, is a key effector participating in Ca(2+)-dependent signal transduction pathways in a number of cellular processes under normal, stress and pathological conditions. However, the expression and the relevance of CN in stress and immune response have not been characterized in crustaceans. Here, we identified the cDNAs that encode the two subunits of CN (termed EsCN-A and EsCN-B, respectively) in Chinese mitten crab Eriocheir sinensis and analysed their expression patterns in response to stress and immune challenges. The catalytic subunit EsCN-A is comprised of 511 amino acids with a theoretical molecular mass of 57.5 kDa and shows 80% sequence identity with human beings CN-A alpha isoform, while the regulatory subunit EsCN-B protein is composed of 170 amino acids with an estimated molecular mass of 19.3 kDa and shares 88% sequence identity with human beings CN-B type 1. Tissue distribution analysis reveals that both EsCN-A and EsCN-B mRNA transcripts are expressed in all tested tissues with the greatest expression in hepatopancreas and the lowest expression in haemocytes. In addition, both EsCN-A and EsCN-B genes could be significantly up-regulated but with different expression patterns by ambient salinity (15‰ and 30‰ salinities) and pH (pH 6 and 8.5) stresses in gill, hepatopancreas, haemocytes, intestine and muscle. Furthermore, EsCN-A and EsCN-B were up-regulated by LPS and Poly(I:C) immune stimulations in E. sinensis haemocytes in vitro. Moreover, EsCN-A and EsCN-B mRNA were significantly up-regulated in haemocytes, gill, hepatopancreas, intestine and muscle in response to Edwardsiella tarda challenge in vivo. Finally, we revealed the importance of EsCN in LPS-induced nitric oxide production in E. sinensis haemocytes. Together our observations suggest that EsCN, the important downstream effector of CaM-mediated signalling pathway(s), may possess vital roles in stress and immune response in the Chinese mitten crab.

Abstract
Molluscan reproduction has been a target of biological research because of the various reproductive strategies that have evolved in this phylum. It has also been studied for the development of fisheries technologies, particularly aquaculture. Although fundamental processes of reproduction in other phyla, such as vertebrates and arthropods, have been well studied, information on the molecular mechanisms of molluscan reproduction remains limited. The recently released draft genome of the pearl oyster Pinctada fucata provides a novel and powerful platform for obtaining structural information on the genes and proteins involved in bivalve reproduction. In the present study, we analyzed the pearl oyster draft genome to screen reproduction-related genes. Analysis was mainly conducted for genes reported from other molluscs for encoding orthologs of reproduction-related proteins in other phyla. The gene search in the P. fucata gene models (version 1.1) and genome assembly (version 1.0) were performed using Genome Browser and BLAST software. The obtained gene models were then BLASTP searched against a public database to confirm the best-hit sequences. As a result, more than 40 gene models were identified with high accuracy to encode reproduction-related genes reported for P. fucata and other molluscs. These include vasa, nanos, doublesex- and mab-3-related transcription factor, 5-hydroxytryptamine (5-HT) receptors, vitellogenin, estrogen receptor, and others. The set of reproduction-related genes of P. fucata identified in the present study constitute a new tool for research on bivalve reproduction at the molecular level.

Abstract
BACKGROUND Invertebrate biominerals are characterized by their extraordinary functionality and physical properties, such as strength, stiffness and toughness that by far exceed those of the pure mineral component of such composites. This is attributed to the organic matrix, secreted by specialized cells, which pervades and envelops the mineral crystals. Despite the obvious importance of the protein fraction of the organic matrix, only few in-depth proteomic studies have been performed due to the lack of comprehensive protein sequence databases. The recent public release of the gastropod Lottia gigantea genome sequence and the associated protein sequence database provides for the first time the opportunity to do a state-of-the-art proteomic in-depth analysis of the organic matrix of a mollusc shell. RESULTS Using three different sodium hypochlorite washing protocols before shell demineralization, a total of 569 proteins were identified in Lottia gigantea shell matrix. Of these, 311 were assembled in a consensus proteome comprising identifications contained in all proteomes irrespective of shell cleaning procedure. Some of these proteins were similar in amino acid sequence, amino acid composition, or domain structure to proteins identified previously in different bivalve or gastropod shells, such as BMSP, dermatopontin, nacrein, perlustrin, perlucin, or Pif. In addition there were dozens of previously uncharacterized proteins, many containing repeated short linear motifs or homorepeats. Such proteins may play a role in shell matrix construction or control of mineralization processes. CONCLUSIONS The organic matrix of Lottia gigantea shells is a complex mixture of proteins comprising possible homologs of some previously characterized mollusc shell proteins, but also many novel proteins with a possible function in biomineralization as framework building blocks or as regulatory components. We hope that this data set, the most comprehensive available at present, will provide a platform for the further exploration of biomineralization processes in molluscs.

Abstract
Calcineurin (CN), a multifunctional protein, mediates the immune response through diverse signaling pathways in mammals, while the function of CN in the immune response of molluscan hemocytes still remains unclear. In the present study, we detected the distribution of CN in various tissues and the expression levels of Pf-CNA and Pf-CNB gene in hemocytes of Pinctada fucata. After the preparation of hemocyte monolayers, we checked the response of enzymatic activity of CN, the degradation level of IkappaBalpha, the activity of iNOS and the production of NO, and IL-2 to the challenge of lipopolysaccharide (LPS) and cyclosporin A (CsA). CN activity in hemocytes was very sensitive to both the stimulation of LPS and the inhibition of CsA. Most importantly, IkappaBalpha degradation in hemocytes was induced by LPS and attenuated by CsA. Consequently, the activity of iNOS was elevated and the production of NO was increased. Additionally, we found that the synthesis of IL-2 was increased by LPS but was apparently weakened by CsA. In vivo bacterial clearance experiments showed that CsA significantly decreased the ability of in vivo bacteria clearance in pearl oyster. All the results revealed, for the first time, that CN mediated the immune response of molluscan hemocytes via activating NF-kappaB signaling pathway.

Abstract
Calcineurin (CN) is a multifunctional protein involved in many important physiological processes in mammalians, but the function of CN in mollusks is still largely unknown. In the present study, through the shell regeneration system, the changes of enzymatic activity of CN were determined in the process of shell regeneration in pearl oyster Pinctada fucata. CN was activated immediately and continuously in the shell regeneration process. The speed of shell regeneration was measured and the ultrastructure of inner shell surface was observed by scanning electron microscopy after inhibiting CN by intramuscular injection of immunosuppresant cyclosporine A (CsA). The results showed that the speed of shell regeneration was delayed and the morphology of calcite and aragonite in the inner shell surface became abnormal when CN was inhibited by CsA. Meanwhile, RT-PCR analysis revealed that the expression of P. fucata BMP-2 in mantle tissue decreased with CsA injection. In vitro secretion level of proteoglycans (PGs) in primary cultures of mantle cells was also decreased when mantle cells were exposed to CsA. Taken together, our results, for the first time, show that CN is involved in the shell formation through regulating the expression of Pf-BMP-2 in mantle tissue, which controls the secretion of PGs/GAGs of the mantle epithelial cells.
